Choosing Together: How Dyadic Negotiation Shapes Adaptive Kitchen Design Preferences for Older Adults with Cognitive Impairment and Their Care Partners

Adaptive technology for older adults with cognitive impairment is typically designed around individual preference, yet most of this population lives and cooks with a spouse or family member. This paper examines a co-design workshop in which four dyads and two individuals (N=10) built kitchen cabinet designs from twenty-one options across five features. Thematic analysis of thirty selections identifies recurring patterns: visual access retained through enclosure rather than open shelving, physical effort treated as a household concern, and automation accepted when predictable. Structured analysis of ten interaction episodes shows how some patterns were negotiated in practice, including care partners contributing embodied constraints distinct from the primary participant, and disagreements resolving through documented deliberation. Together, the two analyses show that adaptive technology preferences are not always individual properties but can be shaped through household interaction. We offer candidate design implications for facilitation protocols and collaborative systems supporting shared decision-making in aging-in-place contexts.

A Reproducible Reality-to-VR Pipeline for Ecologically Valid Aging-in-Place Research

Virtual reality (VR) has emerged as a promising tool for assessing instrumental activities of daily living (IADLs) in older adults. However, the ecological validity of these simulations is often compromised by simplified or low-fidelity environmental design that fails to elicit a genuine sense of presence. This paper documents a reproducible Reality-to-VR pipeline for creating a photorealistic environmental simulation to support a study on cognitive aging in place. The proposed workflow captured the as-built kitchen of the Aware Home building at Georgia Tech using Terrestrial Laser Scanning (TLS) for sub-millimeter geometric accuracy, followed by point cloud processing in Faro SCENE, geometric retopology in SketchUp, and integration into Unreal Engine 5 via Datasmith with Lumen global illumination for high visual fidelity. The pipeline achieved photorealistic rendering while maintaining a stable 90 Hz frame rate, a critical threshold for mitigating cybersickness in older populations. The environment also enables instantaneous manipulation of environmental variables, such as switching between closed cabinetry and open shelving, providing experimental flexibility impossible in physical settings. Participant validation with 17 older adults confirmed minimal cybersickness risk and preserved sensitivity to the experimental manipulation, supporting the pipeline's feasibility for aging-in-place research and establishing a benchmark for future comparative studies.
